Highway Road Widening Construction Technology Based on Short-Distance Sensing Technology

Abstract

Based on the systematic analysis of the current research status of highway widening and reconstruction projects at home and abroad, this paper expounds the purpose and significance of the research. The disease detection and the cause of the disease in the widened highway of the old road were studied, and corresponding treatment measures were put forward. Analyzed the existing problems of highway splicing and widening subgrade, proposed the measures to be taken to solve these problems, and expounded the application of subgrade widening and splicing technology in the widening and extension project of road widening. The improvement of short-distance sensing technology on highway pavement widening construction is studied, and the design theory of roadbed and pavement widening highway is discussed.
